The possibility for the extraction of spring phenological events of boreal evergreen forest from Moderate Resolution Imaging Spectrometer (MODIS) time-series was evaluated in this study. The beginning of the photosynthetically active period, determined from CO2 fluxes measured with the eddy covariance method, was used as primary reference for the onset of growing season (hereafter referred to a...

Open surface water bodies play an important role in agricultural and industrial production, and are susceptible to climate change and human activities. Remote sensing data has been increasingly used to map open surface water bodies at local, regional, and global scales. In addition to image statistics-based supervised and unsupervised classifiers, spectral indexand threshold-based approaches ha...

Remote sensing is a key technology that enables us to scale up our empirical, in situ measurements of carbon uptake made at the site level. In low leaf area index ecosystems typical of semi-arid regions however, many assumptions of these remote sensing approaches fall short, given the complexities of the heterogeneous landscape and frequent disturbance. Here, we investigated the utility of remo...

Since the remote sensing data of MODIS has some advantages of short detection period, wide coverage and open access, it is suitable for large-scale, dynamic agricultural remote sensing monitoring. According to the application requirements of winter wheat acreage extracting in Huang-Huai region, this article analyzes the features of MODIS data and phenological characteristics of crops. Three kin...

Sea ice concentration is an important observation element and a necessary input parameter for the numerical prediction of sea ice. In this study, new method developed inversion (SIC) in Liaodong Bay from MODIS data based on Normalized Difference Water Index (NDWI). By comparing inverted results NDWI WU’s methods, as well observations six shore-based points east coast winter 2016/2017 Landsat 8 ...

This study aims to extract water surface area and lake temperature (LSWT), present long-term spatio-temporal analysis of these variables together with meteorological parameters. Three lakes in Türkiye’s Lakes Region, namely, Lake Burdur, Egirdir, Beysehir, were considered as test sites. The normalized difference index (NDWI) was applied Landsat 5 8 data from 2000 2021 the extent Google Earth En...
